Answer:
180x - x²
Step-by-step explanation:
Since the yard has 360 yd. of fencing, hence the perimeter of Rick's lumberyard has 360 yd.
Given that the yard is x yards long. Let y represent the width of the yard. Hence:
Perimeter of the yard = 2(length + width) = 2(x + y)
Substituting:
360 = 2(x + y)
180 = x + y
y = 180 - x
Therefore the width of the yard is (180 - x) yard.
The area of the yard is the product of the length and the width, hence:
Area (A) = length * width
A = x * (180 - x)
A = 180x - x²
Answer:
20
Step-by-step explanation:
First you need to figure out what they multiplied 6 by to get 60, to do that reverse the operation to make it 60÷6=10. Then you multiply the 10 by the 2 to get 20.
Answer:
20m? im not really sure sorry if im wrong
Step-by-step explanation:
Answer:
x = 2, m = 10, a = 5
Comparing ratios of corresponding sides:
x/4 = 3/6 ==> x = 4*1/2 ==> x = 2
m/5 = 6/3 ==> m = 5*2 ==> m = 10
a/10 = 3/6 ==> a =10*1/2 ==> a = 5
